Melt-spun Co66Nb9Cu1Si12B12 metallic glass ribbon (TC , ≈ 150 K) was used to produce nanocrystalline samples by annealing at 590 and 610°C for 1 h. Their magnetic characteristics were measured in a superconducting quantum interference device magne

A solid solution of (1 −x)(Li2Mn4O8)x(Li1Fe5O8) for 0 0.6. The results are explained by a change of site preference of the Li ion from the tetragonal (A) site atx=0 to the octahedral [B] site atx=1.

An amorphous bimetal ribbon consisting of magnetostrictive (Fe40Ni40B20) and nonmagnetostrictive (Co67Fe4Cr7Si8B12) layers was prepared by planar flow casting from a double‐chamber crucible. The effect of applied tensile stress on hysteresis loops

The controlled crystallization of a Finemet-type amorphous alloy to a nanocrystalline state leads to a known increase in the permeability μ and an immense reduction in its disaccommodation DA. We have found that the maximum of μ is split, and DA ch

The effect of creep annealing on the57Fe enriched Co-rich low magnetostriction amorphous alloys will be reported. Contrary to the Fe-B-base alloys, after creep annealing of the57Fe5Co57Ni10Si11B17 the ribbon axis becomes the hard direction. Both Moss

Using a new design of helium-methane gas-flow detector of conversion electrons for Mossbauer spectroscopy, non-uniform nucleation of the primary α-Fe-Co phase on both contact and free surfaces of the Ar(+H2) annealed amorphous Fe75Co9B16 alloy was o
